Sorry for the delay. I replied to this but never actually hit 'Submit'.
A maximum of 100 waypoints are ever loaded to the aircraft at any given time. So with every flight it is loading the next 100 waypoints. If your mission is 80 waypoints and your first battery flies 40 of them the next 40 will be loaded for battery two.
Any partial progress you make of a mission is saved until you either finish the mission or clear it. This can be an hour or a day later. For data processing this is not idea since the lighting would all be different and the features would not match very well. Breaking a mission up over a long period of time is a recipe for image processing issues.
